sam0/adc: work around ADC errata on SAM D5x/E5x
...
The ADC SYNCBUSY.SWTRIG gets stuck to '1' after wake-up from Standby Sleep mode.
Ignore the ADC `SYNCBUSY.SWTRIG` status bit, this functionality is not used by
the driver anyway.

sam0/adc: add support for samd5x/same5x
...
Add samd5x/same5x support through introducing ADC_DEV as alias for ADC0/ADC1/ADC. ADC (respectively ADC0) is the default if no device is set.

sam0: change ADC periph to return -1 on wrong resolution
...
The common ADC API dictates that a sample call must return -1 on an
incorrect resolution. The sam0 ADC implementation instead threw an
assertion failure.

cpu/sam0: refactor ADC_0 into plain ADC
...
This change is for all boards with a sam0 cpu. This cpu just has one ADC.
It is unnecessary to have defines with ADC_0_ prefix as if multiple ADCs
are possible.
Some defines were not used, such as ADC_0_EN, ADC_0_CHANNELS,
ADC_MAX_CHANNELS, ADC_0_CLK_SOURCE, ADC_0_CHANNELS
Change all ADC_0_ prefixes to ADC_
